Java 中的堆栈移除(对象)方法，示例
原文:https://www . geesforgeks . org/stack-remove object-in-Java-method-with-example/
Java . util . Stack . remove(的对象)方法用于从堆栈中移除任何特定元素。
语法:
Stack.remove(Object o)
参数:该方法接受一个强制参数 o 是堆栈的对象类型，并指定要从堆栈中移除的元素。
返回值:如果找到指定元素并从堆栈中移除，则返回真，否则返回假。
下面的程序说明了 Java.util.Stack.remove(对象 o)方法:
例 1:
// Java code to illustrate remove() when position of
// element is passed as parameter
import java.util.*;
public class StackDemo {
public static void main(String args[])
{
// Creating an empty Stack
Stack<String> stack = new Stack<String>();
// Use add() method to add elements in the Stack
stack.add("Geeks");
stack.add("for");
stack.add("Geeks");
stack.add("10");
stack.add("20");
// Output the Stack
System.out.println("Stack: " + stack);
// Remove the element using remove()
boolean res = stack.remove("20");
// Print the removed element
System.out.println("Was 20 removed: "
+ res);
// Print the final Stack
System.out.println("Final Stack: "
+ stack);
}
}
Output:
Stack: [Geeks, for, Geeks, 10, 20]
Was 20 removed: true
Final Stack: [Geeks, for, Geeks, 10]
例 2:
// Java code to illustrate remove() when position of
// element is passed as parameter
import java.util.*;
public class StackDemo {
public static void main(String args[])
{
// Creating an empty Stack
Stack<Integer> stack = new Stack<Integer>();
// Use add() method to add elements in the Stack
stack.add(10);
stack.add(20);
stack.add(30);
stack.add(40);
stack.add(50);
// Output the Stack
System.out.println("Stack: " + stack);
// Remove the element using remove()
boolean res = stack.remove("100");
// Print the removed element
System.out.println("Was 100 removed: "
+ res);
// Print the final Stack
System.out.println("Final Stack: "
+ stack);
}
}
Output:
Stack: [10, 20, 30, 40, 50]
Was 100 removed: false
Final Stack: [10, 20, 30, 40, 50]
